Physical signs of instability.

S V Paris

    Spine
    |April 1, 1985
    PubMed
    Summary

    Significant joint instability should be detectable through physical examination by a trained professional. If not apparent during examination, its clinical significance is questionable, even if imaging suggests otherwise.

    Area of Science:

    • Orthopedics
    • Biomechanics
    • Physical Examination

    Background:

    • Joint instability is a common clinical concern.
    • Diagnostic methods for joint instability vary, including physical examination and imaging.
    • Differentiating true instability from hypermobility is crucial for accurate diagnosis and treatment.

    Purpose of the Study:

    • To emphasize the diagnostic value of physical examination in detecting consequential joint instability.
    • To question the reliability of imaging in representing true functional joint movements.
    • To highlight the importance of differentiating joint instability from hypermobility.

    Main Methods:

    • Clinical observation and palpation during physical examination.
    • Critical review of the utility of radiographic imaging in assessing functional joint movement.
    • Clinical differentiation between joint instability and hypermobility.

    Main Results:

    • Consequential joint instability is detectable by a trained observer during physical examination.
    • Radiographic findings may not accurately reflect true functional joint movements.
    • Hypermobility can be identified and distinguished from instability through clinical assessment.

    Conclusions:

    • The physical examination is paramount in diagnosing significant joint instability.
    • The clinical existence of instability is questionable if not detected through physical examination.
    • Clinical assessment is key to differentiating instability from hypermobility.
